 Organic electronic applications such as large area displays, organic solar cells, and plastic logic are recent examples of a joined research effort aiming on replacing energy and cost intensive Silicon technology by lightweight, low energy cost materials based on organic molecules. Alan Heeger's nobel price in chemistry for the invention of semiconducting and metallic polymers honors some of these activities.

In terms of physics involved, organic electronics combines the molecular point of view with concepts such as molecular orbits, excitations, and energy levels with solid state physics represented by band structure, mobility, and doping. Charge transport in organic electronics is based on electron and hole transport rather than ionic transport as typical for biomolecular systems, however, also concepts from biology such as energy harvesting inspire organic electronics.

Within the lecture, I will introduce structural, optical and electrical concepts that apply to organic electronics. Prototypical devices such as light-emitting diodes, photo detectors, solar cells, and field-effect-transistors will be discussed and the state of the art will be indicated.

This lecture addresses master students and PhDs interested in electronic aspects of organic materials. The complementary lecture on "Nanostructures" by Hubert Krenner is recommended to cover other important aspects of nano structures, in particular mechanical and optical. A related lab practical may be arranged during the semester break upon individual request. I intend to offer a follow-up seminar during the summer term in 2011.
